In this study 300keV and 1MeV Si vacancy engineering implants have been used to optimise the activation of a 2keV 1×1015cm-2 B implant into SOI. Although the two implants generate a similar areal density of excess vacancies in the SOI top layer, Hall Effect measurements show that low temperature activation is possible to a greater level with the 300keV Si co-implant than with the 1MeV implant. Hall and SIMS data are consistent with a high level of activation of the B at 700°C, with no significant diffusion at the metallurgical junction depth.
